Research Summary

Dr. Kellner researches a wide-range of topics related to physical hydrology, hydro-biogeochemistry, and hydroclimate variability. He is interested in the influences of subsurface hydrology on aquatic and terrestrial ecosystems, and the interactions of competing factors (e.g. anthropogenic and climate impacts) contributing to patterns of water quality and quantity.
